' Specification ofLetters Patent. Patented Aug. Z0, 1919.

Application filed August 10,1918. Serial No. 249,275.

To all whom it may concern:

Be it known that I, Omiznns SJ Asn, a citizen of the United States,residing at Geneva, in the county of Ontario and State of New York, haveinvented certain new and useful Improvements in Wheel-Hubs, of

' which the following is a full, clear, and exact descriptiom'sucli aswill enable other skilled in the art to which it appertains to make anduse the same. f

This invention relates to quick-detachable vehicle wheels of the typewherein an outer "hub, with associated parts, removably fits over aninner hub arranged on the axle, and one of the hubs 15 provided withpins or lugs which project into complementary sockets in the other toeffect transmission of the driving and braking forccsf is eliminated.

One of the objects'of the invention to :provide an improved,construction of sockets in the outer hub adapted to receive pins on theinner hub, and whereby relative wear or mutilation in service of theparts mentioned Other objects and advantages will be in part notedhereinafter in connection. with the following'description oi theuccompanying drawing, which illustrates typical cmbodiments of theinvention, and in which- Figural is an end elevational view of an:

outer hub assembled on an inner hub;

Fig. 2 :is an enlarged sectional view on the .line 2- 2 of Fig. 1; 1 p

Fig. 3 is an end view of a'modificd form of clamping nut; and

Fig. at, a central vertical section thereof.

Referring; more specifically to the draw ing, there is'shown ashectinetal outer. hub

' outer hub by-rigid axially projecting lugs on. the former received incomplcn'ientaryopen- 1 attached, by spokes or otherwise, to thetire-carryingrim and removablyfitting over an itoner driving hub 2. Thelatter is arranged for mounting on the'vchicle axle through interposedbearings. In wheels of this typethe driving and braking forces,

may be transmitted from the inner to ithe ings or sockets in the latter.

As shown in Fig. 2, by the present. invention the outer hub 1 isprovided with a plurality of openings 3 with the walls thereaboutoutturned or inturned to provide bosses 4 beveled, by machining orotherwise, at the inner edge 5 and outer edge 6. Bushings 7, preferablyof hardened metal, are

extended through the openings and are provided at one end with beveledheads 8 and at the other end with threads 9 to receive a threaded nut10, also beveled. The outer diameter of the cylindrical portion of thebushing 7 is preferably less than the in- ,ner diameter of the openings3,wvhercby before nut '10 is tightened, the bushings have a limitedcapacity for eccentric disposal with respect to bosses 4, and wherebythey are automatically centered in correct symmetrical position when thenuts are screwed home.

The inner hub 2 is provided with. asimilar a number of rigid drivingpins 11 extending outwardly and arranged to enter and project throu hbushings 7. When the parts are assembled, with nut 10 tight and theelongated bushings 7 wedged into rigid relation with the outer hub, thebushings present elongated and hardened bearing surfaces to 'take up thestrain and wear imposed by forces transmitted through the driving pins.By reason of this construction the interlock betweenthehubs to preventtheir relative rotation is permanently reliable and the partslin contactpractically free from sub- Jection to wear or mutilation in servicewithattendant knocking. or other disadvantage.

In the modified form shown in Figs. 3 and l the clamping nut 10 is splitaxially at 12, whereby, as the nut is tightened on the bushing itsbeveled engagement'with wall 5 ef fectswedging with the latter and alsocon traction and locking on the bushing. In both forms it is to be notedthat the headed bushing affords an enlarged and hardened bearing surfaceto receive the driving pins the weakened metal of the outer hub' 1 isavoided, and the attendant described functional advantages insured.I'I'aving described my invention, what I claim as new anddcsire tosecure by Letters Patent is: 1

1. In a device of the character described, in combination, a wheel hubhaving spaced so t at direct contact of the latter against axialapertures therein to receive driving pins, the side walls about saidapertures being beveled, bushings disposed through said.

apertures and having; beveled heads to fit against correspondingportions of said walls,

and clamping nuts threaded on the opposite ends of said bushings andprovided with beveled ends to fit against the (Kn-responding I portionsof said walls whereby said bushings may be wedged firmly in position toafford elongated bearings tor the driving pins,

2. In a device ofthe character described, in combination, a wheel hubhaving spaced axial apertures therein to receive driving pins, the sidewalls about said apertures beingbeveled, bushings disposed through saidaper ures and of slightly lesser diameter thaiuthe saine and havingbeveled heads to tit a gainst ,eorres iomling portions of said Walls,and elan ping iiujs threaded on the oppositee ids oi said busl'iings andprovided.

' /ltll. beveled-ends to fit against the correto reniovably fit on saidinner hub and haw 111g correspondingly placed Sockets to re eeive saidpins, said sockets comprising a pertures in the outer hub with the wallsthereabout beveled, headed bushings extending through saidapertures,.andsplit clamping nuts threaded on said bushings and provided with beveledportions to bear against e0r-,

responding portions of said walls whereby said bushings may be wedged inposition and said clamping nuts automatically e011: {i'aeted thereonwhen tightened.

v In testimony whereof I afiix my signatuie in the presence of twowitnesses.
